According to our results, the Ailuropodinae would be characterized by the following synapomorphies: a tall coronoid process; a high articular process; and alisphenoid canal present. Parent taxon: Ailuropodinae according to J. Abella et al. Click through the PLOS taxonomy to find articles in your field. Is the Subject Area "Miocene epoch" applicable to this article? The three extinct ailuropodin genera are recovered as a monophyletic clade, sister taxon of the extant Ailuropoda. Yes In order to test clade robusticity, a bootstrap analysis with 1,000 replicates was performed using the branch-and-bound search option. The Indarctini includes the species of the genus Indarctos [40], [41], [42], which was widely distributed though Northern Africa, Eurasia and North and Central America during the Late Miocene (MN9-MN13; [40], [43]). Despite long-lasting disputes about the phylogenetic position of Ailuropoda, especially due to dietary-driven convergence in the dentition with the lesser panda (Ailurus fulgens) [2], [3], it is currently well-established on molecular grounds that the former corresponds to the living sister-taxon of other extant bears [8], [9], [10], [11],[12],[13], being classified in its own subfamily (Ailuropodinae) [11], [13] or tribe (Ailuropodini) [14]. Yes (2012) Kretzoiarctos gen. nov., the Oldest Member of the Giant Panda Clade. Yes lufengensis from Lufeng (6.9-5.8 mya) [5], [6], [7], [14], [15]. It is generally considered that Ailuropoda descended from the Asian, Late Miocene ursid Ailurarctos [5], [7], [14]. A cladistic analysis based on a morphologic data matrix for living and fossil ursids recovered a single most parsimonious tree of 157 steps (Figure 3). The type species of Agriarctos, Ag. The lack of resolution among this subfamily may be attributed to the retention of many plesiomorphies shared with both the successive stem ursids Ursavus and Ballusia, as well as with the other most primitive members of the Ailuropodinae (Indarctos, Kretzoiarctos and Agriarctos). PLoS One 17:e48985. Il semblerait que son ancêtre le plus vieux soit Kretzoiarctos beatrix. A new genus of extinct ursid belonging to the giant panda lineage, Kretzoiarctos gen. nov. (Ursidae: Ailuropodinae: Ailuropodini), is here described on the basis of new fossil remains from the Spanish site ACM/C6-Camí (Vallès-Penedès Basin). 2012;7(11):e48985. A cladistic analysis of fossil and extant members of the Ursoidea confirms the inclusion of the new genus into the Ailuropodinae. We also thank Borja Figueirido for the photographs of U. maritimus and M. ursinus, and Francisco Pastor for the loan of the skeleton of Tremarctos ornatus. Le panda géant (Ailuropoda melanoleuca), emblème du WWF, est connu dans le monde entier. Departamento de Geología Sedimentaria y Cambio Climático, Instituto de Geociencias; UCM-CSIC (Universidad Complutense de Madrid-Centro Superior de Investigaciones Científicas), Madrid, Spain, University of California, Berkeley, United States of America, Received: May 23, 2012; Accepted: October 1, 2012; Published: November 14, 2012. Moreover, Kretzoiarctos precedes in time the previously-known, Late Miocene members of the giant panda clade from Eurasia (Agriarctos and Ailurarctos). Although some authors attributed the holotype of A. gaali to Indarctos cf. Holotype: left P4, NV-2-42 (Figure 1; 3a–c) from NV II. gaali, was originally based on a mandibular fragment with p3-m2 [16] from the Turolian (MN12, Late Miocene) locality Hatvan (Hungary) [19]. The role of the purported ailuropodine Agriarctos, from the Miocene of Europe, in the origins of this clade has been generally dismissed due to the paucity of the available material. These species include I. vireti (Iberian Peninsula, MN9) and I. arctoides (Europe MN10-11), with a relatively limited temporal range and geographic distribution, as well as I. punjabiensis (MN10-13), with a Holarctic distribution, and the endemic insular I. laurillardi from Baccinello (MN12), whose taxonomic status is yet to be determined. Les raisons de son extinction sont inconnues; l’une des hypothèses est qu’il n’a pas survécu à la crise du Messinien. Depuis peu, des recherches ont permis d’en savoir plus. 1, Right mandible with canine and p2–m3 IPS46473 from ACM/C6-Camí in labial (a), lingual (b) and occlusal (c) views; 2, Broken P4 IPS46473 in labial (a) and occlusal (b) views; 3, Left P4 NV-2-42 (holotype) in labial (a), occlusal (b) and lingual (c) views; 4, Right M1 NV-2-42 (paratype) in labial (a), occlusal (b) and lingual (c) views from Nombrevilla 2. https://doi.org/10.1371/journal.pone.0048985.g001. Therefore Character 1 in the matrix would be character 0 in this list. IPS46473 corresponds to a partial right mandible that preserves the canine and the lower cheek teeth (see measurements in Table 1). Among the Ailuropodinae, two distinct subclades can be distinguished: that composed by Indarctos species (I. vireti, I. arctoides and I. punjabiensis), which are here included in a distinct tribe, Indarctini tribe nov. (type genus Indarctos); and the one including the remaining ailuropodines (tribe Ailuropodini). A bootstrap analysis (Figure 3) shows that most of the clades recovered by the most parsimonious tree are relatively well supported (i.e., bootstrap values higher than 50%). Kretzoiarctos beatrix, Agriarctos beatrix (Agriarctos beatrix Abella, 2011), Synonyms:  Ursavus depereti Fraile, 1997, Ursavus primaevus Álvarez Sierra, 2003, Size: 1.3 m in length, 50 cm in height, 60 kg of weight, Time period: the Miocene of Europe (11 million years ago), Typical representative: Agriarctos beatrix Abella, 2011. That is why the mission of this project is to be a guide to the world of prehistoric fauna - undiscovered and incredibly beautiful. [33], p. 78); Ursavus primaevus (in ref. A similar anomalous result is obtained by our analysis regarding tha lack of support of the Ursus clade, whose monophyly is supported by molecular studies [13]. The local stratigraphic series of ACM (els Hostalets de Pierola, Catalonia, Spain), situated in the Vallès-Penedès Basin (NE Iberian Peninsula), is a 250 m-thick stratigraphic composite succession including more than 200 fossil vertebrate localities and spanning about 1 myrs (from ca. The monophyly of the Ursidae total group (bootstrap value 79) and of the Ursidae crown-group (bootstrap value 66) are well supported, whereas in contrast the successive stem position of Ursavus species is not supported. Note: Character number start in 0. PLoS ONE 7(11): Type species: Kretzoiarctos beatrix (Abella et al., 2011) comb. Departament de Geologia, Àrea de Paleontologia, Universitat de València, Burjassot, Valencia, Spain. Like above, the divergent dietary adaptations displayed among the ursine bears [39] could be the cause of this ambiguity. Мешкав у середині міоцену (12,5—11,5 млн років тому). Wrote the paper: JA DMA. Competing interests: The authors have declared that no competing interests exist. 22 mya [8], 19 mya [12] or 18 mya [2]). Most recently, an older, new species of this genus, Agriarctos beatrix, was described on the basis of dental remains from the late Aragonian (MN8, Middle Miocene) locality of Nombrevilla 2 (NOM2, Calatayud-Daroca Basin, Spain) [20], formerly attributed to Ursavus primaevus [25]. The premolars (p2–p4) have a single main cusp that displays a duniform shape, as well as poorly-developed mesial and distal accessory cusps. A maximum-parsimony analysis was performed using the branch-and-bound method, with Canis lupus as the outgroup. The material from Nombrevilla 2 (NV 2) includes an upper carnassial and an M1 (Figure 1, 3–4) and it is housed in the Museo Nacional de Ciencias Naturales – Consejo Superior de Investigaciones Científicas (MNCN-CSIC), Madrid [20]. Besides Ailurarctos, the extinct genus Agriarctos, from the Miocene of Europe [5], [16], [17], [18], has been also attributed to the Ailuropodinae. Even though C. lupus is not a member of the Ursidae, its cranial, mandibular and dental morphologies are supposed to be similar to the ancestor of the Arctoidea, and therefore a quite accurate choice as an outgroup for this analysis. The hypodigm also includes the new material described here: partial right mandible with c1–m2 and associated P4, IPS46473 (Figure 1; 1–2 and Figure 2) from ACM/C6-Camí. Kretzoiarctos beatrix pesait environ 60 kg contre en moyenne 100 kg pour le panda géant (Ailuropoda melanoleuca). Thus, the upper carnassial in Ursavus is triangular and always lacks a parastyle, whereas in Kretzoiarctos it shows a well-developed parastyle (although not yet separated from the paracone). The fossil remains of Kretzoiarctos reported here, however, at least conclusively document the occurrence of ailuropodines by the Middle Miocene of Eurasia, with Ballusia and Ursavus displaying a successive basal position with regard to crown ursids as a whole.
